Description

例えば、図９に示すように、軽量の熱可塑性、熱硬化性及び／又はガラスの繊維層（１１１）、例えば、織りファブリック、編みファブリック、薄い不織物、紙、縫い層、縫いマットを、より強い、より間隙を多く有する(more porous)な層、例えば、ポリマ状のスクリム、又はガラススクリム（１０４）、或いは、ルーズに編んだ又は織った支持層で、積層し、接着し、縫製し、縫い付ける形で編んで、織って、溶融接着し、又はこれらの技術を組み合わせて連結さて、スラリの浸透抵抗と芯部の補強の両者を提供する（本明細書に援用するＡｌｔｅｎｈｏｆｅｒ他の米国特許第４，５０４，５３３号及びＫｎａｕｆ他の米国特許第３，９９３，８２２号参照）。スクリム（１０４）は、接着結合材又は糊づけを介して又は介さずに、また、例えば、ファイバ、ロービング、ヤーンが含有した、編んだオープンメッシュ、又は、一般的に縦方向ファイバと横方向ファイバが交差状に連結した不織布にすることが出来る。このように、高密度で、軽量な層（１１１）は、石膏やセメントスラリへの限られた又はごく僅かな浸透を提供し、他方、スクリム（１０４）は、芯部（１０１）の中に埋め込まれて、該芯部（１０１）に対する良好な機械的な接着力とボード（１００）により大きな全体的な力を提供する。さらに、スクリム（１０４）は、芯部（１０１）に付着する前に、前記軽量かつ高密度な層を補強することができるので、前記軽量、高密度な層（１１１）は、安価なものであることができ、かつ、セメントボード連続生産ライン自体の苛酷さに耐えうるだけの引っ張り強度をもつ必要もない。したがって、スクリム（１０４）は、前記軽量で、高密度な層（１１１）を補強するように作用して、該層のねじれに耐性をもっているので、当然に、ボードの連続製造中、外装層全体に亘って補強する。場合により、スクリム（１０４）の硬化した芯部側に、軽量層（１１７）を追加して張り付けることも出来る。両軽量層（１１１）及び（１１７）は、同一の密度である必要はなく、また、同一の繊維材を含有している必要もなく、かつ、各層を被覆しても、しなくてよく、また、何れかに含浸させても、させなくてもよい。 For example, as shown in FIG. 9, a lightweight thermoplastic, thermoset and / or glass fiber layer (111), such as woven fabric, knitted fabric, thin nonwoven fabric, paper, sewing layer, sewing mat, and more strong, has many more gaps (more Porous) layer, for example, polymer-like scrim or glass scrim (104), or knitted loose or woven in the support layer, laminated, adhered, sewn, knitted in the form of sewing, woven, melt bonded, or connected now, provides both reinforce the penetration resistance and the core portion of the slurry (Altenhofer other U.S. patents are incorporated herein by combining these techniques No. 4,504,533 and Knauf et al U.S. Pat reference No. 3,993,822). Scrim (104) is not through to through an adhesive binder or gluing or, also, for example, fiber, roving, yarn contained, woven open mesh, or, generally longitudinal fibers and transverse direction A non-woven fabric in which fibers are connected in a cross shape can be formed. Thus, the dense, lightweight layer (111) provides limited or negligible penetration into gypsum and cement slurry , while the scrim (104) is in the core (101). embedded in, providing greater overall force for good mechanical adhesion and board (100) with respect to the core portion (101). Furthermore, the scrim (104) prior to adhering to the core (101), it is possible to reinforce the light weight and high-density layer, the light-weight, high-density layer (111) is intended inexpensive It is not necessary to have a tensile strength that can withstand the rigors of the cement board continuous production line itself. Thus, the scrim (104) is in the light, and acts so as to reinforce the high-density layer (111), because it has a resistance to the layer of the twist, in course, continuous production of boards, the entire outer layer Reinforce over. In some cases , a lightweight layer (117) can be additionally attached to the cured core side of the scrim (104). Both lightweight layers (111) and (117) need not have the same density, need not contain the same fiber material, and may or may not cover each layer, Moreover, it does not need to impregnate any.

好ましい合成（複合）外装材は、石膏やセメントスラリに対する間隙を有する(is porous to)スクリム（１０４）、織り構造、編み構造を含む。理想的には、スクリム（１０４）は、１インチ当たり６×６端部を有する単純織り又は結合格子構造を含むが、１インチ当たり約４×４から約１０×１０の端部のサイズも許容される。スクリム（１０４）用の好ましいファイバサイズは、経済的であり、また、広く入手可能な、約６８テックス（Ｇ７５；ＥＣ９６８）である。また、スクリム（１０４、若しくは、これと同等な層）は、上述のものと化学的に同一な若しくは相違する糊（サイジング）を含んでもよい。軽量層（１１７）及びスクリム（１０４）に塗布する糊は、最終用途のためにカスタマイズされることが出来る。例えば、スクリム（１０４）は、石膏芯部に対してより高い親和性を有する、カルボキシルスチレンアクリル樹脂又はアクリル混合物で処理することが出来、他方、軽量層（１１７）の結合樹脂を、疎水性の添加剤で処理してスラリの浸透に抵抗してもよい。セメント芯部（１０１）、及び被覆剤又は飽和剤（１０７）に役立つものであると示唆される他の添加剤及び他の樹脂組成物を、前記結合剤中に用いることも出来る。 Preferred synthetic (composite) exterior material has a gap with respect to the gypsum and cement slurry (IS Porous-to) scrim (104), including woven structure, a knitted structure. Ideally, the scrim (104) comprises a simple woven or bonded grid structure with 6x6 ends per inch, but sizes from about 4x4 to about 10x10 ends per inch are acceptable. Is done. A preferred fiber size for the scrim (104) is about 68 tex (G75; EC968), which is economical and widely available. Also, the scrim (104 or equivalent layer) may include glue (sizing) that is chemically the same as or different from that described above. The glue applied to the lightweight layer (117) and scrim (104) can be customized for end use . For example, the scrim (104) has a higher affinity for the gypsum core, can be treated with carboxylated styrene-acrylic resins or acrylic mixture, while the binder resin of the light weight layer (117), the hydrophobic It may be treated with additives to resist slurry penetration . Other additives and other resin compositions suggested to be useful for the cement core (101) and the coating or saturant (107) can also be used in the binder.
